Airbag for vehicle

Abstract

An airbag for a vehicle of the present invention includes: an inflator; and an airbag cushion, in which first and second slits are formed in the airbag cushion so as to be spaced apart at a predetermined distance, and one end of the inflator is inserted into the airbag cushion through the first slit, and then protrudes to the outside of the airbag cushion through the second slit, and as a result, the inflator is securely and conveniently coupled to the airbag cushion.

What is claimed is: 
     
       1. An airbag for a vehicle, comprising:
 an inflator; and 
 an airbag cushion in which the inflator is installed, 
 wherein first and second slits formed in the airbag cushion so as to be spaced apart at a predetermined distance, 
 end of the inflator is inserted into the airbag cushion through the first slit, and then protrudes to the outside of the airbag cushion through the second slit, 
 wherein a plurality of studs is formed on the inflator so as to be spaced apart from each other in a length direction of the inflator, and 
 a plurality of holes through which the plurality of studs protrudes to the outside is formed in the airbag cushion so as to be spaced apart from each other between the first and second slits, 
 wherein a separation distance between the plurality of holes is shorter than a separation distance between the plurality of studs. 
 
     
     
       2. The airbag of  claim 1 , wherein a length of the second slit is one-half of a circumference of the one end of the inflator or smaller than a diameter of the one end of the inflator. 
     
     
       3. The airbag of  claim 1 , wherein a reinforcing fabric, which covers a portion where the inflator is installed, is attached to the airbag cushion. 
     
     
       4. The airbag of  claim 3 , wherein the reinforcing fabric includes a squib hole, wherein a squib formed at the one end of the inflator protrudes to the outside through the second slit and the squib hole. 
     
     
       5. The airbag of  claim 4 , wherein a plurality of studs is formed in the inflator, and a plurality of stud holes through which the plurality of studs protrudes is formed in the reinforcing fabric. 
     
     
       6. The airbag of  claim 5 , wherein a stud hole among the plurality of stud holes, which is at least adjacent to the squib hole, is formed in a rectangular shape that has a longer length in an upward and downward direction. 
     
     
       7. The airbag of  claim 5 , wherein a separation distance between the plurality of stud holes is shorter than a separation distance between the studs. 
     
     
       8. An airbag for a vehicle, comprising:
 an inflator; and 
 an airbag cushion in which the inflator is installed, 
 wherein first and second slits formed in the airbag cushion so as to be spaced apart at a predetermined distance, 
 end of the inflator is inserted into the airbag cushion through the first slit, and then protrudes to the outside of the airbag cushion through the second slit, 
 wherein a reinforcing fabric, which covers a portion where the inflator is installed, is attached to the airbag cushion, 
 wherein the reinforcing fabric includes a squib hole, wherein a squib formed at the one end of the inflator protrudes to the outside through the second slit and the squib hole, 
 wherein a plurality of studs is formed in the inflator, and a plurality of stud holes through which the plurality of studs protrudes is formed in the reinforcing fabric, 
 wherein a diameter of a stud hole among the plurality of stud holes, which is spaced farthest apart from the squib hole, is smaller than a diameter of the stud.
